[asterisk-users] Cutting noise and voice
Very Good day to everybody, I had a problem with an implementation that recently made ??in my Company, dealing in a Grandstream gateway which will enable echo cancellation but until you hear noise point appears in the middle of words creating noise interference, when you disable the echo in this device may not hear much sound but the echo is uncomfortable. I added these lines to each sip of my sip.conf, but the echocontinues. echocancel = yes echocancelwhenbridged = yes If anyone knows how or echo cancellation parameters should be encuenta so that the noise did not delete some parts of words of voice. Also add the codec G711 and alaw, since this is the one using the phones.

You cannot echo cancel SIP. Removing echo must be done before PSTN is converted into SIP. i.e. your PSTN/SIP gateway. -----Original Message----- From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Diego Alejandro Sanchez Quiroga Sent: Thursday, October 20, 2011 3:45 PM To: asterisk-gui at lists.digium.com; asterisk-users at lists.digium.com Subject: [asterisk-users] Cutting noise and voice Very Good day to everybody, I had a problem with an implementation that recently made ??in my Company, dealing in a Grandstream gateway which will enable echo cancellation but until you hear noise point appears in the middle of words creating noise interference, when you disable the echo in this device may not hear much sound but the echo is uncomfortable.
